Modified Bitumin Roofing


Consider the modified bitumen roof for your next project. It has a life expectancy of at least 25 years. It is worth your investment if you have a damaged or aging roof. Cool Roofs Inc. can help you enjoy your new roof at a great price in New Braunfels or Austin. 

Our customers enjoy this style because it provides improved energy efficiency. The roof also holds up against the elements. Created in the 1960s, this roofing style is a cost-effective replacement for a built-up roofing system.

Building owners with low-slope or flat roofs can benefit. Asphalt bitumen is infused with polymers and fiberglass reinforcements. The composition then sticks to a commercial flat roof.

Understanding Modified Bitumen Roofing

Modified bitumen roofing occurs through two styles of installation: peel-and-stick and torch-down methods. Both options are cost-effective and weather-resistant. 

  • Building maintenance workers often use the peel-and-stick option. It saves money, but installation is less successful.
  • The torch-down method is more effective. The installation specialist uses an open flame to melt the membrane of the roll roofing layers.
  • Overall, the torch-down method provides consistent protection from water penetrating the surface. It also deflects UV rays.

The team at Cool Roofs Inc. is here to help. We will help you determine the best installation for your building. 

APP or SBS? Choosing Your Roofing.

A sloped roof or a flat roof is the ideal candidate for the torch-down installation. The customers who choose this option will use either APP modified bitumen on SBS modified bitumen. Either option can work.

The difference is in the base materials. 

  • APP roofing materials are more rigid after installation. A plastic known as atactic polypropylene makes up the membranes.
  • SBS installation materials have more elasticity. The membranes are made of styrene-butadiene-styrene, a synthetic rubber.

When to Choose APP Modified Bitumen Roofing 

APP modified bitumen roofing is a top choice in areas with temperate weather. 

  • Prepare for a plastic-like appearance
  • Enjoy increased UV-ray protection 
  • Experience the benefits of water mitigation

When to Choose SBS Modified Bitumen Roofing 

SBS modified bitumen roofing benefits commercial, industrial, and institutional buildings with low-slope roofs. 

  • Enjoy one of the most trusted options
  • Take advantage of reliability and affordability 
  • Adapt to sudden temperature changes

Underneath The Surface

There are multiple layers within this roofing system; increased protection and efficiency are the results. Rain and wind won’t be the cause of destruction. 

Enjoy easy and affordable installation, durability, flexibility, and more. Here is a glimpse of the many layers:

  • Insulation layer

Low-slope or flat roofs need high-quality insulation. It helps to prevent heating and cooling losses.

  • Vapor barrier

The installation expert adds this layer above the insulation. It helps to prevent moisture, which can weaken support or grow mold.

  • Overlay board installation

Modified bitumen roofing requires an expert to install a protective cover board. It goes over the vapor barrier and insulation.

  • Base sheet installation

The base sheet is the first layer of the roof material. 

  • Cap sheet installation

The cap sheet clings to the base sheet. Together, they protect the structural integrity of the building. 

  • Parapet and other flashing

Anything that rises above the low-slope or flat roof must have flashing and sealants. They prevent water penetration. 

Frequently Asked Questions

What is the lifespan of a modified bitumen roof?

If you maintain the roof, expect 25 years or more. You may only enjoy ten years if maintenance is poor.

How does it compare to the BUR system?

Built-up roof systems go back to the 1800s. Builders used heavy layers of tar or asphalt as insulation for a flat roof. The bitumen roof is lightweight and has vapor barriers.

Do you have to inspect this roofing style?

Yes! Inspectors can see early signs of damage. Regular repairs help to prolong the lifespan. After a high-wind event or one that caused damage, check your roof.
